1.1 How to use this component operating manual

Structure of the

IQ S

ENSOR NET

operating manual

Fig. 1-1 Structure of the IQ SENSOR NET operating manual

The IQ SENSOR NET operating manual has a modular structure like the

IQ S

ENSOR NET itself. It consists of a system operating manual and the

operating manuals of all the components used.

Please file this component operating manual into the ring binder of the

system operating manual.

1.2 Terminal function of the MIQ/T2020 PLUS

The MIQ/T2020 PLUS terminal is an extension component for the

IQ S

ENSOR NET system. It can be docked on – and removed again from

– any free lid front of an MIQ module as a mobile control unit. The

docking is performed by a simple manual action without the need for

any tools.

Information that describes the behavior of the terminal after the docking

maneuver can be stored in each MIQ module. This information

includes:

l The name of the respective measurement location

l A selection of measured values that should be displayed at this

measurement location.

This function (local identity function) can be used, e.g. to quickly find

sensors for calibration on site. The information is transmitted by the two

upper contacts on the back of the terminal.

1.3 MIQ/T2020 PLUS controller operation

Automatic safety

function

The MIQ/T2020 PLUS has a controller that takes over the basic

functions of the IQ S

ENSOR NET controller if it fails and thus

considerably increases the operational safety of the system. For this

purpose, the MIQ/T2020 PLUS automatically and regularly saves the

system configuration during the regular terminal operation.

System configuration The system configuration contains the allocation of the sensor numbers

and all settings of the following menus:

l Settings of sensors and diff. sensors

l Settings of outputs and links

l Edit list of sensors

l Edit list of outputs

l Measured value recording (datalogger settings).

In the IQ S

ENSOR NET, the system configuration is saved in the

controller (MIQ/C184 or MIQ/MC).

Functions in the MIQ/

T2020 PLUS controller

operation

The MIQ/T2020 PLUS controller operation comprises all basic

functions of the IQ S

ENSOR NET. Relay and current interfaces work

without restrictions.

Restrictions in the MIQ/

T2020 PLUS controller

operation

In the MIQ/T2020 PLUS controller operation, the following functions

cannot

be supported:

l Editing the system configuration. Apart from date and time, all

settings in the Settings menu are locked and cannot be released for

changing

l Adding new sensors and input or output modules

l Continuing the datalogger operation of the main controller

l Continuing the Profibus, Modbus, or modem communication of the

main controller (due to missing interfaces).

A redundant data logging function can be set up with the aid of the

MIQ/IF232 interface module.

Manual saving function Apart from automatically saving the system configuration, the system

configuration can be saved manually in the MIQ/T2020 PLUS at any

time during regular terminal operation. This function can be used for the

MIQ/T2020 PLUS controller operation and for the following tasks as

well:

l Making a safety copy of the system configuration, for example

before changing settings that may have to be undone again (testing

new settings).

l Transmitting the system configuration to a second IQ SENSOR NET

system. This facilitates the quick commissioning of several similar

systems.

2.1 Authorized use

The authorized use of the MIQ/T2020 PLUS consists of its use as a

control unit with redundant controller function in the IQ S

ENSOR NET.

Please adhere to the technical specifications given in chapter 7

T

ECHNICAL DATA. Only operation according to the instructions in this

operating manual is authorized.

Any other use is considered to be unauthorized. Unauthorized use

invalidates any claims with regard to the guarantee.

2.2 General safety instructions

The MIQ/T2020 PLUS is constructed and inspected according to the

relevant guidelines and norms for electronic instruments (see chapter

7 T

ECHNICAL DATA).

It left the factory in a safe and secure technical condition.

Function and

operational safety

The failure-free function and operational safety of the MIQ/

T2020 PLUS is only guaranteed if the generally applicable safety

measures and the special safety instructions in this operating manual

are followed during its use.

The failure-free function and operational safety of the MIQ/

T2020 PLUS is only guaranteed under the environmental conditions

that are specified in chapter 7 T

ECHNICAL DATA.

Safe operation If safe operation is no longer possible, the MIQ/T2020 PLUS must be

taken out of operation and secured against inadvertent operation.

Safe operation is no longer possible if the MIQ/T2020 PLUS:

l has been damaged in transport

l has been stored under adverse conditions for a lengthy period of

time

l is visibly damaged

l no longer operates as described in this manual.

If you are in any doubt, contact the supplier of your MIQ/T2020 PLUS.

Note

Follow the installation instructions in the I

NSTALLATION chapter of the

system operating manual.

Up to three terminal components can be docked on an IQ S

ENSOR NET

system.

3.2.1 Software requirements

The MIQ/T2020 PLUS requires for its operation an IQ S

ENSOR NET

main controller with the software version 2.04 or higher. Full

functionality is available when using a main controller with the software

version 2.70 or higher. Using older main controller versions there are

small functional restrictions when retransferring the stored settings (for

details, see section 4.3.3).

3.2.2 Docking and removing a terminal

The mobile MIQ/T2020 PLUS terminal is docked on the lid of any free

MIQ module. The terminal can be docked while the system is running

without the measurement being interrupted.

Note

For the temporary docking of a mobile terminal, do not remove the

whole contact cover. Leave it hanging on the side of the MIQ module.

After removing the terminal, replace the cover again to protect the

contacts.

Fig. 3-2 Docking the terminal

Removing the terminal To remove the terminal, press the locking lever and pull the terminal

forwards.

1 Pull the cover off the contacts (pos. 1 in Fig. 3-1) on the lid of

the MIQ module.

2 Place the terminal on the module lid. To do so, insert the flap

on the back of the terminal into the slot on the door hinge of the

module. Then, pull back the interlocking lever (pos. 2 in

Fig. 3-2), place the terminal completely on the module and

release the interlocking lever.

3.2.3 Initialization

When the system is running, the terminal automatically starts to

operate as soon as contact is established to the IQ S

ENSOR NET. In the

first phase, the background illumination of the display switches on and

the terminal is initialized. This process may last a few seconds. The

following display appears (Fig. 3-3):

Fig. 3-3 Display during the initialization process

The terminal then switches to the measured value display.
